Abstract: This paper draws a brief sketch of the main features of French recommendations for Ultra-High Performance Fiber-Reinforced Concretes (UHPFRC), drafted by an AFGC work group composed of all the private and publics organizations working on these new types of material. The purpose of these recommendations is to give a framework for use of UHPFRC in civil engineering. The concretes here concerned have a compressive strength over 150 MPa up to 250 MPa and fiber incorporation so as to ensure a ductile behaviour under tensile stress and to replace the conventional reinforcing steel. The document is based on a synthesis performed by an AFREM group, on the French Electricity Board specifications and on the personal experience of members of the work group. It is composed of three parts :
· A first part dealing with UHPFRC characterization giving specifications about the mechanical properties to be obtained. This part also deals with the special checks during production and with concrete placing methods.
· A second part which focuses on design and calculations methods for UHPFRC engineering structures, taking into account fibers participation and structures without conventional prestressing or reinforcing steel.
· A third part devoted to UHPFRC durability which describes influential material properties like transport mechanisms or physical and chemical processes in comparison with Reinforced Concrete or HPC properties.
It also includes a complete list of references.
